Cs, i i <br /> Working To Restore Nature <br /> IRECONEMW24DATIONS <br /> RESNA, on behalf of the responsible party, is prepared to implement the revised groundwater <br /> monitoring program which was approved in PHS/EHD correspondence dated August 4, 1993 <br /> The correspondence indicated that the revised monitoring program should be implemented <br /> beginning with the first quarter 1994. RESNA maintains, due to the general decreasing trend <br /> of dissolved contaminants in wells MW4 and MW5 over the past five consecutive quarters and <br /> the apparent lack of contaminants in downgradient wells MW1 and MW6, that immediate <br /> implementation of the revised monitoring program is warranted ,-RESNA respectfully requests <br /> PHS/EHD reconsider the timeframe for implementation of the revised monitoring program l <br /> If you have any questions or comments regarding this protect, please contact John Lane at (209) <br /> 838-3507. <br /> Sincerely, <br /> RESNA Industries Inc. <br /> n P Lane <br /> ' Project Geologist <br /> Gregory P.
